SecurityPermissionAttribute Class

Allows security actions for SecurityPermission to be applied to code using declarative security. This class cannot be inherited.

Namespace:  System.Security.Permissions
Assembly:  mscorlib (in mscorlib.dll)

[SerializableAttribute]
[AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple = true, 
	Inherited = false)]
[ComVisibleAttribute(true)]
public sealed class SecurityPermissionAttribute : CodeAccessSecurityAttribute

The SecurityPermissionAttribute type exposes the following members.

  NameDescription
Public methodSecurityPermissionAttributeInitializes a new instance of the SecurityPermissionAttribute class with the specified SecurityAction.

  NameDescription
Public propertyActionGets or sets a security action. (Inherited from SecurityAttribute.)
Public propertyAssertionGets or sets a value indicating whether permission to assert that all this code's callers have the requisite permission for the operation is declared.
Public propertyBindingRedirectsGets or sets a value that indicates whether code has permission to perform binding redirection in the application configuration file.
Public propertyControlAppDomainGets or sets a value indicating whether permission to manipulate AppDomain is declared.
Public propertyControlDomainPolicyGets or sets a value indicating whether permission to alter or manipulate domain security policy is declared.
Public propertyControlEvidenceGets or sets a value indicating whether permission to alter or manipulate evidence is declared.
Public propertyControlPolicyGets or sets a value indicating whether permission to view and manipulate security policy is declared.

Public propertyExecutionGets or sets a value indicating whether permission to execute code is declared.
Public propertyFlagsGets or sets all permission flags comprising the SecurityPermission permissions.
Public propertyInfrastructureGets or sets a value indicating whether code can plug into the common language runtime infrastructure, such as adding Remoting Context Sinks, Envoy Sinks and Dynamic Sinks.
Public propertyRemotingConfigurationGets or sets a value indicating whether code can configure remoting types and channels.
Public propertySerializationFormatterGets or sets a value indicating whether code can use a serialization formatter to serialize or deserialize an object.
Public propertySkipVerificationGets or sets a value indicating whether permission to bypass code verification is declared.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

  NameDescription
Public methodCreatePermissionCreates and returns a new SecurityPermission. (Overrides SecurityAttribute.CreatePermission().)
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

The scope of the declaration that is allowed depends on the SecurityAction that is used.

The security information declared by a security attribute is stored in the metadata of the attribute target and is accessed by the system at run time. Security attributes are used only for declarative security. For imperative security, use the corresponding permission class.

When you use the SecurityPermissionAttribute class, follow the security action with the permission(s) that are being requested. Each security permission that can be requested, as defined in the SecurityPermissionFlag enumeration, has a corresponding property in the SecurityPermissionAttribute class. For example, to demand the ability to access unmanaged code, follow the demand statement with the property setting that is being requested, as follows: SecurityPermissionAttribute(SecurityAction.Demand, UnmanagedCode=true).

NoteNote

An exception to the equivalence between the SecurityPermissionFlag enumeration and the SecurityPermissionAttribute properties is that the AllFlags enumeration value is represented by the Unrestricted property (inherited from the SecurityAttribute class). To demand all security permissions, specify Unrestricted=true.
